• Heat, bend, cut, and grind steel as part of heavy fabrication work, following technical specifications and job requirements.
• Read and interpret blueprints, technical drawings, and welding symbols to plan and execute welding and fabrication tasks accurately.
• Conduct minor fit-up work independently, preparing components for welding and ensuring proper alignment and joint configuration.
• Operate heavy-duty fabrication tools and equipment, including grinders, torches, plasma cutters, air chisels, needle scalers, and oxy/fuel cutting torches.
• Use air arc (arc air) equipment to gouge and prepare weld areas and perform repair work on heavy equipment components.
• Safely operate overhead and jib cranes and apply proper rigging techniques when moving and positioning large steel components.
• Inspect welds for quality, strength, and compliance with specifications, and make adjustments or repairs as needed.
• Apply pre-heat and post-heat procedures where required to maintain material integrity and weld quality, particularly on thick and hard plate.
• Demonstrate a strong commitment to safety, following zero-harm behaviors and contributing to a world-class safety culture.
• Collaborate effectively with team members, supporting a positive and cooperative work environment.
• Successfully complete and pass a welding test as part of the hiring process and maintain high welding standards throughout employment.
